C-1 Method 1–Download Updated Software
The preferred method for resolving serial port compatibility issues is to download software updates for your
product from
www.us.anritsu.com .
C-2 Method 2–Trying a Different USB Port
1. Disconnect the USB end of your power sensor from your computer (or USB hub).
2. Connect the USB power sensor to a different USB port on your computer. Connecting to a USB hub tends
to increase the port numbers, so connecting directly to the computer’s USB port usually provides the best
result.
3. Open the Device manager to see if the new port assignment is between COM1 and COM16. If it is NOT,
return to step 1 and connect to a different USB port. If the port assignment is between COM1 and
COM16, the problem has been resolved and no further action is required.
C-3 Method 3–Remapping a Serial Port
A serial port may be remapped to a different number, such as changing a serial port from COM19 to COM5.
This may be needed if method 1 above does not result in a serial port assignment between COM1 and COM16
or if you prefer to use a USB hub or a specific USB port on your computer.
1. Open the System Properties by going to Start | Settings | Control Panel | System, or simultaneously
pressing the Windows and Pause keys.
